Quality Systems Checklist for 2016 TNI Laboratory Standard

TNI's Laboratory Quality Systems Expert Committee has prepared an Excel spreadsheet to provide guidance to laboratories and laboratory assessors in assessing laboratories to TNI Standard EL-V1, Management and Technical Requirements for Laboratories Performing Environmental Analyses (2016) and is making this checklist available for download.

In order to achieve accreditation, laboratories are required to have an official copy of TNI Standard ELV1, Management and Technical Requirements for Laboratories Performing Environmental Analyses (2016). This document contains copyright protected language from ISO/IEC 17025:2005. Once you have obtained a copy of the TNI Standard, under the fair use clause of U.S. copyright law, you may download the Quality Systems Checklist. By clicking on the box below, you are confirming that you have obtained an official copy of TNI Standard ELV1, Management and Technical Requirements for Laboratories Performing Environmental Analyses (2016)and will be able to show the copy to the assessor during the on-site assessment.

TNI is working with the NELAP Accreditation Bodies to incorporate any state-specific enhancements into the generic quality system checklist. By completing the affidavit below, you will also be able to access any of these state-specific checklists that have been developed.
